Beit known that I, GEORGE W. PENNIsToN of North Vernon, in the county ofl Jennings and State of Indiana, have invented certain new and usefulImprovements in Presses for Cotton, Hay, Ste.; and I do herebydeclareing and releasing the doors of the press-box,

and in fastening the pulley-block tothe rock` shaft, to relieve it ofsome of the pressure in working the press.

In the accompanying drawings, A is the base of the press-box, connectedto the top bars, B B, by the posts G C C G', to make a strong frame, thetop bars, B, being connected bythe cross-bars D D. The planking for thesides of the press'is fastened to the posts C C, and the top C of thepress-box is arranged to vibrate on the rod C, so that it can be openedto fill the press and then closed and secured by theV rod C2. The door Eis hinged at E and secured by a catch at E2. There are two doors like Fone on each side-hinged in the bars I)"D2, and when closed are held bythe lockingfbar F^ and clevis F2, hinged to the endof the bar Fl', andshown open in dotted lines in Fig. 2.` When the doors F are closed andthe clevis placed in the position shown at F2, parallel with and on thebar F, to hold the doors to, the clevis is held parallel with the bar bythe key F2, (shown in Fig. 3,) with a forked end, which is placed uponthe clevis and bar, and

4'hinged to the traverse-rod F, which vibrates the key and releases theclevis, so that the elasticity of the article pressed throws theV doorsopen.

The plunger G is shown in elevation in Fig.

y4c. It is made long enough to allow the` togglethe ways G3 on the sidesof the; press-box..

(Shown by dotted lines infFigsQl and 2.):1 In.)` f order topreventgtheplungerfrom rocking and?. making the bales of unequalthickness, I put in` 1 e the braces G* G,to stiffen it and hold theplunl f 1 e j ger parallel to the endof `the press, and the@` roller G5,under the point of connection .withfyh the togglelevers,relievestheplunger of lnznichi"l of the friction which wouldotherwise impede theprogress of the plunger. The toggleflevers l l G' G are connected to thethree toggle-barsH` L H H `by the .pin H, one ofthe bars supporting thepin between the levers and the other twoj i bars outside th eleversrenderingit very strong.. g

'and making it a most powerful press. They e e lower ends ofthetoggle-bars Hj are fastenedto the rock-shaft H2, which shaft turnsinll the V blocks H2, between the posts C,and carries tl1`e` 1 1 arm H,and screwI, whichstrikesythe rod Ff` l and moves it so astorelease thekeylliei` when l l the bale being pressed is small enough, and let f l ethe doors of the pressopem 1Thepulley-blockyg I', Fig. 5, is fastened`tothe rock+shaft H2, and l ,y

is provided with projections `I2,to hold the`pul-`l ley from swingingtoward therock-shaft, soas; ,1b. j to bind the rope whenthepressis drawnopens f e The rope I2 is fastenedto oneof` `the toggle-le:l l f vers G',and passes around-:the pulley in" the"` block I and up overfthepulleybetweenlthes e toggle-levers G', anddownunder the pulley in l theblock J, fastened to thebase `A, and" fromjl y .y that to thewindlass-barrelJ, uponwhich itis j 3Q wound by a horse attached tothelever .12,"fast-g r ened tothe shaft J2e-of the windlass shown in l Fig.8. The windlassbarrel Kl is right under.

the windlassibarreld, and is connected to the plunger' G bythe rope 3K',which. draws3 back the plunger after` the bale pressedllwhasl l beenbound. The ,shaft J2 is supported by the; 3 frame K2,`and is arrangedtoturn freely in bothf r y e l windlass-barrels, and is provided withaclutch-` l;

block, K3, which iscarried from one windlass-" barrel to the other byraising and lowering` y the barrels by the lever L, so as, to `lock thenz `l barrels to the shaft alternately towork the ltog"` gles, and pressa bale or` retractthe press, each; u windlass-barrel having a cavity init," as shown e in Fig. 7, for the block K2. The lever\L,which1 1 l;

raises and lowers the windlassfbarrels, `has itsf` fulcrum at L', andiscrossedbygthe.lever` L2V,;` which is locked down by the `latch L3,Fig.1, so `1 as to hold the barrel K up tothe block Kat i. `Byl l l. e `1swinging the latch one side, both Windlasses Willvdeseend, so as to lockthe upper one to the shaft. This arrangement of Windlasses allows thehorse that carries the lever J2 to travel all the time in one direction,and saves the time and labor of turning twice for eachbale pressed. Tofill this press the doors E and C are opened and the press-box lled withthe cotton or other material to be pressed, and the doors closed andfastened, as heretoforedescribed. The Windlass is then Worked to drawdown the toggle-levers until the screw I operates the bar FL andreleases the doors F F, `when the bale is ready to receive Vits hoops,after Which it may be removed.

My'improvements make a press cheaper in yproportion to its capacity,which may be:

Worked with a given pressure, With less power,

and in far less time than any other press made prior to the date of myinvention.

' I believe I have described my improvements in presses so as to enableany person skilled in the art to make and use them. I Will 110W statewhat Idesire to secure by Letters Patent, viz:

ll. The clevis F2, constructed substantially as described, incombination with the bar F and key F3, for locking and releasing thedoors of the press-box, as specified.

2. Fastening the block'I to the rock-shaft H2, so as torelieve it ofsome of the pressure in Working` the press, as set forth.
